THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 394,290, dated December 11, 1888.

Application filed May 17, 1888.

To all whom it may concern.-

Be it known that 1, 'WILLIAM H. PARDEE, of Col11n'11;)ia,in the county of Brown and Territory of Dakota, have invented a new and Improved Thill-Coupling, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which- Figure is a plan view, with parts broken away, of my improved thill-cmlpling. Fig. is an inverted plan view. Fig. 3 is a front elevation, and Fig. l is a transverse section taken on line as .0 in Fig. 1.

Similar letters of reference indicate corrcspending parts in all the views.

The obj eat of my invention is to construct a thill-coupling provided with a simple and efficient coupling-bolt fastener to prevent ratt ling, and which cannot become accidentally loosened.

My invention consists in the combination, 7

with the thill-iron and clip attached to the axle of a carriage, of a mortised coupling-bolt, a pair of spring-actuated bolts, and a support for the same, all as hereinafter more tullydescribed.

The clip A, which receives the thill-iron B, is attached to the axle in the usual way by means of the rounded and threaded ends u and cross-bar (,1 and nuts I), received on the ends a. The cross-bar C is prolonged beyond the clip A and rounded and threaded to receive nuts 1' (1. Upon the prolongation of the cross-bar C is secured the bolt-holder D between the nuts d. The said bolt-holder is provided with apertured ears e, which extend upwardly at: the sides oi the ears ol the clip A.

To the thill-iron l the clip A, and the ears 6 of the bolt-holder l) is titted the couplingbolt E, having mortises g near opposite ends and outside of the ears c of the bolt-holder. In the boltholder D are formed tubular guides Within the guides 72, and surrounding the bolts F, are placed spiral springs i, which rest against shoulders in the upper ends of the guides 72 and bear against collars j, carried by the bolts, the said collars being adjustable by nuts 1:, received on the 1 Serial No. 274,145. (No model.)

selves, and are tapered to form keys m for entering the mortises 5 The edges of the keys m slide in grooves a in the ears c.

By raising the bolts I" the bolt E may be withdrawn from the clip and thill-iron; but it cannot be removed without raising both of the bolts, as either bolt is sutiicient to hold the coupling-bolt in its position in the coupling.

It will be observed that my improved fastening can be attached to an ordinary coupling in the manner described, or it may be formed integrally with the coupling.

Having thus described my invention, I claim as new and desire to secure by Letters Pat ent- 1. In a thill-coupling, the combination, with a clip, of a mortiised coupling-bolt and a springactuated bolt carried by the clip and engag- 1 ing the mortise of the said coupling-bolt, sub

stantially as described.

The combination, with the clip A and thill-iron B, of a mortised coupling-bolt, E, and two independentspringactuated bolts, F, substantially as specified.

The combination, with the clip A, provided with ears f, the thill-iron B, and the coupling-bolt E, having mortises g, of the bolt holder 1) and the spring-actuated bolts F, carrying the tapering keys in, adapted to fit into the mortises ot' the bolt E, substantially as specified.

4. In a thill-coupling, the combination, with a clip and its cross-bar, ot' a bolt-holder secured to the said cross-bar and provided with apertnred ears projecting upward at the sides of the ears of the clip and with tubular guides to receive spring-actuated bolts, substantially as described.

5. In a thill-coupling, the combilnttion, with downwardly parallel with the bolts them- D, provided with the ears 8 and the tubular guides 71, of the niortised coupling-bolt E and the springaetuated bolts F, provided with the horizontal arms Z, having downwardly-proj ecting keys in on their ends for entering the mortises ot' the coupling-bolt, substantially as herein shown and described.
